Other chorioretinal scars, left eye

This code signifies the presence of a chorioretinal scar in the left eye that is not specifically categorized elsewhere. These scars represent areas of healed damage to the choroid and retina, often resulting from inflammation, infection, trauma, or degenerative processes. The scar tissue can affect visual acuity depending on its size and location.

Use this code when documentation specifies a chorioretinal scar in the left eye, and the etiology or specific type of scar is not further defined (e.g., not a post-inflammatory, post-traumatic, or post-surgical scar). This code is appropriate when the physician's notes indicate "chorioretinal scar, left eye, unspecified" or "other chorioretinal scar, left eye."

• Ensure the laterality (left eye) is clearly documented.
• Avoid using this code if a more specific chorioretinal scar code (e.g., H31.01- for post-inflammatory) can be assigned based on documentation.
• Always review the medical record for the underlying cause of the scar; if known, code the underlying condition first, if applicable, and then the scar.
